Airtac SED Double Rod Cylinder SED50X50SH
The AirTAC SED Double Rod Cylinder SED50X50SH is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 50mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X50SH
The AirTAC SED50X50SH is a double-acting, double-rod ISO 15552 profile cylinder with a 50mm bore and 50mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract. This gives you exactly 825 N of force in both directions at 0.5 MPa. The extruded aluminum barrel omits external tie rods, ensuring a clean, dimensionally interchangeable ISO 15552 footprint.
This specific configuration uses a Viton (FKM) seal to operate in environments up to 150 C. The integrated -S magnet allows position tracking via DMSE electronic or CMSE reed sensors. You also get field-adjustable air cushioning at both ends to manage end-of-stroke kinetic energy.

| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 30 mm |

Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 kgf |
Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SED Double Rod Cylinder SED50X50SH Is Used
High-Temp Transfer Chucks
Drives 50mm gripper chucks on hot stamping lines. The Viton seal survives 150 C ambient heat, while the twin rods provide 825 N of equal push/pull force without load rotation.
Rear-Rod Cam Actuation
Uses the protruding rear rod to trip a mechanical limit switch on a packaging machine. The M16x1.5 rod end simplifies custom cam mounting for dual-side mechanism timing.
Chemical Valve Isolation
Actuates diverter valves near heated process lines. The FKM seal resists thermal degradation, and the 1154 N output at 0.7 MPa securely shifts heavy internal plugs.
Is the Airtac SED Double Rod Cylinder SED50X50SH the Right Cylinder?
Select this 50mm bore when you need equal push and pull forces for a 50mm transfer cycle, yielding 825 N both ways at 0.5 MPa. If your mechanism requires less force, step down to the 40mm bore (528 N both ways). If you need more thrust, step up to the 63mm bore (1402 N both ways). Unlike a single-rod SE cylinder, the twin rods on this SED prevent load rotation and let you mount a rear cam or secondary tool. Remember that a standard SED will drift on air loss; for fail-safe holding, use a BSED rod-lock cylinder or external brake. To replace an existing ISO 15552 unit, match the 50mm bore, 50mm stroke, PT1/4 port, and mounting hardware.
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED50X50SH FAQ
Because the double-rod design has equal piston areas on both sides, force is identical in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The SED profile cylinder supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. It omits the FB, CA, CB, and CR mounts. Ensure you leave rear-rod clearance, as the overall length is longer than a single-rod SE cylinder.
